Answer:
x = -15
Step-by-step explanation:
The expression for (r-s)(x) is found by subtracting s from r. That difference is
. The expression for (r+s)(x) is found by adding them, which is
. Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results.
. There you go!

Answer:
8.5%
Step-by-step explanation:
I=PRT
85= 2000*r*0.5
85=1000r
0.085=r
8.5%
They are not in proportion, since its 6:9 round it down (2:3) so pretend the 6 are apples and the 9 are oranges
Every 2 apples there are 3 oranges
So having 9 apples what is that?
2 x ? = 9
2 x 4.5 = 9
So if you want to keep 2:3 you have you times the oranges by 4.5 aswell!
3 x 4.5 = 13.5
So since it is 9:12 not 9:13.5 they are not in proportion
